Grandstream Networks DP730 - General Call Features and Safety; Dial Codes for Call Management

Configuration:
The PTT feature is always enabled on the base station, to use this feature, users need to enable the PTT on the handset at:
Handset Menu → Preferences → PTT → set “Enabled”.
Enable PTT
Also, to use PTT, the DP722 needs a dedicated button to push and then to talk, user can choose to use either LSK (Left
Softkey) or RSK (Right Softkey) in Shortcuts settings. (If you forgot to enable the PTT, when you press the PTT softkey, it will
redirect you to the setting to enable it before you can use it.)
Set a Softkey for PTT
Users can configure the “DECT PTT Silence Timer” on the Web UI at → DECT → General Settings. When a PTT call is
established, any handset that enabled the PTT feature will automatically join the PTT call. if there is no one talking, after a
certain time, the PTT call will be closed. This timeout setting is to determine how long the PTT call will be closed after being
idle status. If set to 0, the timer will be disabled, and the PTT will remain forever until all parties exit the PTT call.
Call Features
The DP Handsets support traditional and advanced telephony features including caller ID, caller ID with caller Name, call
forward, etc.
